To all whom it may concern:

Be it known that I, ERNns'r LITTMAN, a subject of the Emperor ofAustria-Hungary, residing at the borough of Manhattan, m

h. the countyof New York, city and State of New York, have inventedcertain new and useful Improvements in Machines for Making PlaitedPaper, of which the following isa s ecification.

It 's invention relates to a machine for forming ornamental paper, andin the present embodiment the invention is apphed to a machine forforming tucked or planted a r., I

M P principal object of the invention is to produce an automatic machinecapable of producing a neat ornamental paper and capable of operating ata high speed.

One of the ob ects is to produce such a W machine which shall be ca ableof prmua. ing what is known as p aited or tucked paper in largequantities and wlththe machine operating at a high speed, withouttearing the paper. I

Further objects of the invention wlllappear more fully hereinafter.

The invention consistsof the general combination of parts and detailshereinafter described all of which'contribute to produce W an efi'ectivemachine for producing ornamental paper.

A referred embodiment of my invention will described in the followingspecification while the broad scope of the invention $5 will be pointedout in the appended claims.

Fig. 3 isanelevation showing the opposite side from that shown in Fig. 1. Fig. {Iis a fragmentary side elevation and partial section showin details ofthe tucker device. Fig. 5 is a si e elevation showingother details. Fig.6 is an elevation showing details of the knife. Fig. 7 is a plan showinga small portion of paper such as produced by the machine. Fig. 8 is anedge view of a portion of the finished pa er.

'lhe paper stock is preferably drawn from a supply roll 10 in. acontinuous web 10 passmg between guide means such as guide and feedrollers 11 and 12 the former of j which may be continuously driven at aslow speed by a suitable belt 13 passing around specification ofJDetterc Patent.

a suitable pulley 14 on the shaft of roller 11 and driven from the mainshaft 15.

The tucks are preferably formed by displacing transverse portions of thesheet laterally progressively to develop in excess of the materlal thenoperating 11 on this displaced portion to form a dou le edge and thenpressing the doubled edges to form the -tucks, meanwhile the paper ispreferably feed ng forward intermittently.

In order to accomplish this I prefer to guide the paper web 13 along theupper face of a substantially horizontal table 16. Near the upper faceof the table I provide means such as a pusher or shoe 17 preferablypivoted at 18 and continuously rocked or reciprocated laterally withrespect to the plane of the paper. In other words the paper passes overthe shoe and every time the shoe moves down it leaves a dis lacedportion or pocket of the material. he shoe 17 is preferably reciprocatedby means of a rocking frame 22 pivotally supported on the frame 19 ofthe machine at 20 and also supported on a continuously rotatin cam 21which lets the usher drop sudden y at each revolution. T e pusher may beconnected with the frame 22 by a pin and slot connection 23. While thedisplaced pocket of the material is projecting up from the sheet it isengaged by a tucker device preferably comprising a plate 24: disposedabove the sheet near the table; the-forward edge 25 of this tuckerengages the displaced part of the sheet and moves forward at this pointin the direction in which the sheet is moving.,- The upper part of thedisplaced portion then falls in the pusher and forms a doubled edgeextending transversely across the sheet.

In order to.rec1procate the tucker I prefer to mount it on an arm 26 ofa bell crank lever 27 rocked by a link 28 adjustably attached in aradial slot 29 in a crank disk 30 on the aforesaid shaft 15.

Means is rovided for holding the tucker oif of the eet on the backstroke of the tucker preferably consisting of an arm 31 having a commonpivot support at 32 with the tucker plate, a cam 33 on shaft 15 engagesthe under side of arm 31 and holds it and the tucker plate up as thetucker recedes. A spring-pressed block and roller 34 hold the arm 31down on the cam.

The means for pressin the doubled edges to form them into tuc preferablycomprises two rollers 35 and 36 rotatably mounted one above the otherthe roller 36 being pressed by a spring 33 down on to roller 35. The web10 passes between these rollers which press the doubled edges or foldsflat. In order to permanently hold the tucks in place I prefer toprovide a tape or tapes 38 which pass down from sup 1y rolls 39 and 40.These tapes are prefera ly dry-gummed tapes, and as they pass down thegummed face is moistened by suitable fountain brushes 41 suppliedconstantly with water from a reservoir 42. These tapes are thus renderedadhesive on one face and they then pass overthe roller 36 and between itand roller 35. This presses the adhesive side of the tapes against thetucks which secures them in place. In order to feed the paperintermittently forward I prefer to intermittently rotate the rollers. 35and 36. This is preferably accomplished by means of a ratchet and pawl43 and 44, the pawl mounted, on an arm which is constantly rocked by alink 45 (see Fig. 3), said link being actuated by a rock lever 46pivoted at 47 and'constantly rocked by an eccentric rod 48 from shaft15. The spring 37 is provided with a suitable let-off device 49 forholding the roller 36 raised when desired.

After leaving the rollers 35 and 36 the paper moves past a knife 50which is operated automatically to cut the web into suitable lengths.For this purpose I prefer to provide a countershaft 51 (see Fig. 6),driven from shaft 15 and carrying a cam 52 which intermittently raisesthe lower blade 53 to cotiperate with the upper blade 54 like shears.

In order to adapt the tape rolls 39 and 40 to the making of differentwidths of tucked paper I prefer to mount the roller 40 on-a slidingbracket 55 which is adjustable transversely of the machine because ithas threaded engagement with a transverse adjusting screw 56. This screwcan be rotated from hand-wheel 57 (see Fig. 2).

The tucker plate is preferably formed with slots 58 on its forward edge.

50 In order'to maintain the tapes in suitable Inasmuch as many changescould be made in the above construction, and many apparently widelydifferent embodiments of my invention could be made without departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawings shall beinterpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the followingclaims is intended to cover all the generic and specific features of theinvention herein described and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween.

I claim:

1. In a machine for forming tucked paper, in combination, a table onwhich the sheet lies, a reciprocating pusher moving up and down near thesurface of the table to displace the paper upwardly into a transversepocket, a reciprocating tucker consisting of a plate projecting in thedirection the paper advances and engaging said pocket with its edge toform a doubled transverse edge in the paper, and rollers for pressingthe doubled edges to form tucks and means for supplying a tape passingbetween said roll ers to adhere to the tucks of said sheet, and meansfor intermittently rotating said rollers to feed the sheet forward.

2. In a machine for forming tucked paper, in combination, means forforming transverse tucks in the sheet, means for holding and attachingbinding tapes to the paper, and means for adjusting the holding meansfor the tapes to adapt the same to sheets of different width.

3. In a machine for forming tucked paper, in combination, means forforming transverse tucks in the sheet, a supply roll for a tape, meansfor drawing the tape from the roll and for attaching the same to thesheet, a bracket carrying the said roll, and a transverse adjustingscrew engaging said bracket for adjusting the same across the machine.

4. In a machine for forming tucked paper, in combination, means forforming transverse tucks in the sheet, a supply roll for a tape, meansfor drawing the tape from the roll and for attaching the same to thesheet, a bracket carrying the said roll, a transverse adjusting screwengaging said bracket for adjusting the same across the machine, aknife, and means for automatically actuating the same to cut the sheetinto smaller sheets.

In testimony whereof I affix my signature.
